Radical SR3
I've got a few sets of these for the track car, all medium compound, all with 5mm tread. I've had a set fitted to my track wheels (15") for a trip to the Ring in a few weeks. All being well I'll be doing 2 days there in total on track..around 15-20 laps. Given the Cup is quite light (sub 900kg) and I'm quite a smooth driver, what's the average length of these tyres? I'm driving there and back on the stock 16s.
